Patti Carr and Lara Olsen are now in charge of 90210.

The writers/producers have taken over for Rebecca Sinclair and, before the pair gets into some major season four scoopage, they have a message to deliver to fans: you'll be seeing plenty of Trevor Donovan this fall.

"I know there is sort of a technical difference in Trevor's deal but he's a major character for us," Carr tells TV Guide. "We love Teddy and we've got a really great story line for him.  

That storyline will involve Teddy coming out to his family. What else do Carr and Olsen have to say about season four? A LOT. Check out the following quotes/teases:

The kids won't all be going to the same college, Carr says: "Our overall concept for the season is that when you graduate from high school you launch yourself into your new adult life. You go through a process of trying to figure out who you are, and ultimately, your friends are the people who know the real you and they become your family."

Teddy will not be dating Marco any longer.

Can Adrianna be redeemed? That will be a major focus early on, Carr previews: "When she comes into the premiere, she feels like the person she has to approach first is Silver. That is going to be more than a one-episode process. That's where she begins to realize that this is going to take longer than she thought. She's going to have to work harder for it. She spent her summer trying to be a good person, going out into the world and trying to redeem herself and show what a changed person she is."

Might Naomi NOT be pregnant?!? "We can say that we don't think of Naomi as a character who's a big liar, and we do know she has real feelings for Max," Carr mysteriously says.

Ivy and Raj will still be married when we next see them.

An outsider will play a role in Silver and Navid's relationship.

What about Liam and Annie? "When he returns, he has made a very interesting decision regarding his relationship with Annie, and it's definitely something viewers will be interested in," Carr says.
